The starter motor on your STS Sigma cranks the engine to start the combustion cycle. Clicking without cranking, intermittent starting or complete failure means the starter needs replacing.
Frequently asked questions
What should I check when buying a replacement starter motor for the Cadillac STS?
Match the exact engine code and transmission type (manual/automatic) of your STS Sigma, as starters differ. Check whether the solenoid and mounting hardware are included.
Is a remanufactured starter motor reliable?
Yes – remanufactured starters with new brushes, solenoid contacts and bearings are tested to OEM specs and offer good value compared to new units.
